Soil Temperature and Moisture

Model 107 Temperature Probe:This durable and versatile probe measures air, soil, or water temperature from -35°C to 50°C with a ±0.2°C tolerance over the 0° to 50°C range.

CS655 Soil Water Content Reflectometer:This multiparameter smart sensor that uses innovative techniques to monitor soil volumetric-water content, bulk electrical conductivity, and temperature. Volumetric Water Content is estimated using the Topp Equation for a range of 5% to 50% with a ±3% accuracy and a precision of < 0.05%.

Wind

Model 014A Met One Wind Speed Sensor:This three-cup anemometer is designed for coninuous operation in adverse conditions and monitors wind speed from 0 to 45 m/s with an accuracy of 0.11 m/s and a starting threshold of 0.45 m/s.

Leaf Wetness

Rainfall

Rain Gauge Tipping Bucket TR-525I Rainfall Sensor:This remote tipping bucket rain gauge measures 0.2 mm of liquid precipitation for every bucket tip, with an accuracy of 1.0% up to 50 mm/hr. As water is collected, the tipping bucket fills to the point where it tips over and empties in preparation for additional measurements.

Solar Radiation

CS300 Pyranometer:This sensor uses a silicon photovoltaic detector mounted in a cosine-corrected head to measure 0 to 2000 W/m² of sun plus sky radiation in the spectral range of 300 to 1000 nanometers, which encompasses most of the shortwave radiation that reaches the surface of the Earth.
